330mm Front Big Brake Kit

The Ksport Slimline Audi RS4 Big Brake Kit (BKAU150-332SO) is engineered to address the common issue of aftermarket big brake kits not fitting with aggressive wheel fitments on factory body vehicles. Its innovative Slimline Caliper design, based on OEM single-side floating piston caliper thickness, allows for compatibility with wheels that have very limited brake caliper clearance. This makes it an ideal choice for enthusiasts seeking enhanced braking performance without compromising their chosen wheel aesthetic. The kit features lightweight forged one-piece aluminum calipers, which are constructed from a solid billet to ensure strength and eliminate weak spots. The calipers house aluminum pistons protected by heavy-duty seals capable of withstanding racetrack temperatures, ensuring smooth operation and preventing drag. Opposed-piston design promotes consistent brake pad grip and wear, while high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates are standard. This design also minimizes rotor warping due to heat expansion and acts as a heat sink for longer service life. D.O.T. compliant stainless-steel braided brake lines are also standard, providing a firmer pedal feel and quicker response by eliminating line expansion under pressure. The kit comes complete with two forged, monoblock aluminum calipers, two lightweight two-piece slotted rotors, a set of SC5 street brake pads, two stainless steel brake lines, and all required mounting components and hardware. Optional upgrades include RCI Race Pads for extreme track conditions and various custom caliper color options, including premium high polish finishes and over 20,000 custom color choices. The kit is backed by a 12-month limited warranty covering manufacturer defects. This system is appropriate for 17-inch wheels and above and is noted to fit 2WD vehicles.
